"The pharmaceuticals company Shire, a perennial target of takeover talk, was buoyed by renewed bid speculation yesterday. The US drugs giant Pfizer was reported to be considering a £13-per- share offer for its smaller British peer. Investors were excited and Shire's stock soared to an early intra-day high of 1,035p – an increase of 92p, or almost 10 per cent, on Thursday's closing price."
